Description

Technical Field

[0001] The utility model relates to the technical field of cable protection, and particularly relates to a cable moisture-proof protection structure. Background Art

[0002] A cable is a device for transmitting electric energy or signals, usually composed of several or several groups of wires. In order to ensure the long-term and effective operation of the cable, it is often necessary to consider moisture-proof of the cable during the cable laying process. For example, a patent with the application number 202223112421.2 discloses a moisture-proof cable protection pipe, which can not only ensure moisture-proof of the cable, but also recycle the heat generated by the cable, and has good practicability.

[0003] However, the moisture-proof performance of the cable not only depends on the cable shell, but is also restricted by the moisture-proof performance of the cable connection. At present, after the cable is connected, electrical tape is often used for winding isolation and moisture-proof, but its moisture-proof performance is poor.

[0004] Therefore, we propose a cable moisture-proof protection structure. Content of the Utility Model

[0005] The purpose of the utility model is to provide a cable moisture-proof protection structure to solve the above problems, which has the advantages of double-layer moisture-proof, good moisture-proof performance, easy disassembly, etc., as described in detail below.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A cable moisture-proof protection structure provided by the utility model includes a housing structure and a wiring structure;

[0008] The housing structure includes two symmetrically arranged upper and lower housings. A wiring cavity is arranged in the middle of the housing. An annular water-blocking cavity for filling water-blocking powder is arranged outside the wiring cavity. The annular water-blocking cavity wraps the wiring cavity.

Connecting holes are provided in the middle of the connecting ears to realize the connection and installation between the connecting structure and the housing, laying a foundation for the connection between the two housings.

[0011] Preferably, the sealing structure includes two symmetrically arranged sealing rings on the left and right and two symmetrically arranged sealing gaskets in the front and back. The outer side of the sealing ring is fitted with the mounting hole, and a main wire inlet is provided in the middle of the sealing ring. The left and right ends of the sealing gasket are respectively connected to the two sealing rings to realize the fitting installation between the outer side of the sealing ring and the mounting hole, laying a foundation for the connection and installation between the sealing structure and the housing structure.

[0012] Preferably, a sealing groove corresponding to the sealing gasket is provided on the housing, and the sealing gasket is fitted with the sealing groove to realize the fitting installation between the sealing gasket and the sealing groove, laying a foundation for the connection and installation between the sealing structure and the housing structure.

[0013] Preferably, the wiring structure includes two symmetrically arranged metal wiring posts on the left and right.

A wiring hole that penetrates from left to right is provided in the middle of the metal wiring post, and a locking structure is provided at the upper end of the metal wiring post to realize the connection and installation between the wiring structure and the housing and ensure the smooth wiring between the cables.

[0014] Preferably, the locking structure includes a compression screw, and the compression screw is threadedly connected to the middle of the metal wiring post. A plastic handwheel is provided at the upper end of the compression screw to realize the connection and installation of the locking structure, laying a foundation for the locking and fixing of the cable wiring.

[0015] Preferably, a threaded hole corresponding to the compression screw is provided on the metal wiring post, and the threaded hole communicates with the wiring hole to ensure that the compression screw extends into the wiring hole and ensure the compression and locking function of the compression screw on the cable.

[0016] The beneficial effects are as follows:
